Wrong. Fun is an emotional experience. Animals are driven more by it than humans. They do what they like doing and avoid what they don't, even if in the long run doing 'not-fun' stuff would be more beneficial to them. To a dolphin, fun is the essential driver of its behavior.
The human idea of fun is the same, but unlike animals we don't need the instant gratification of something being 'fun' to motivate us. Much of what we do is not fun, but we know that doing it will eventually make our lives better, eg. growing crops or manufacturing products for future use.
Animals don't need instant gratification of something being 'fun' to motivate them, something can be 'not fun' for them, and motivate them (as it is for us).
For animals, as for humans something can be funny or not funny.
What in particular depends on the particular animal species, and on the particular occasion.
A tautology is not just a truth that everyone knows, it defines itself - which makes it worthless for analysis. You are saying that what is fun is fun, which tells us nothing about what is fun and what isn't, like saying 1 = 1.
I am saying exactly that, and the practicality of "fun is fun" is that for humans it is hard to convince humans that something not fun for them is fun to them, but it is possible to convince them that something they think is not fun, but haven't experienced, may be fun, if they gave it a shot.
If you want to have a fun life with other people, better do what is fun for all in the group together, and what is fun for each individually alone.
But people don't only do what is fun for them - in fact most of the time they don't. In modern economies we work at jobs we often don't enjoy in order to earn enough credit to purchase the things we need to survive. If we are lucky we get enough to have some fun too.
Any economic theory that relies on having fun as a motivator is bound to fail, because that isn't what mostly drives us.
you need to survive to have fun, but surviving doesn't mean you have fun, you still need to have fun to have fun.
And this phrase means that you will know it when you are having fun.
Now, regarding "fun isn't what mostly drives us", if that is so then what mostly drives us is not fun, in which case you have humans trying to convince you should live a life mostly without having fun...now that isn't very sensible is it ?
How is that? In the same way that being irresponsible isn't that sensible also.
And someone who is trying to say that in their lives they are not trying to have fun, they usually aren't that honest.
Nonsense. I have more fun than most people, but even I have to work occasionally to pay the bills. Due to Covid-19 my regular job was put on hold so I had to take what I could get. The job I got was very boring and physically demanding, but paid well. After 2 weeks I started suffering from RSI, but stuck to it because I needed the money. That job is finished now so I am recovering (and having fun!) until the money runs out - when I will probably have to do more not-fun stuff.
So I had to endure pain for a considerable time, and I had to be patient. If I had only been motivated by fun and tried to avoid pain, I would not have stuck to the job and not earned the money that allows me to have fun now.
Let's simply say you don't have more fun than most people...why?
Because you don't know how other people's lives feel to them, this is why.
Perhaps you have more, perhaps you have less, if you think you know that and fun isn't what mostly motivates you, as you wrote above, you need to guide me another way to your way of thinking.
Too expensive = too expensive? A worthless tautology.
"Something is "too expensive" for one when one decides that it is too expensive for him/her, for whatever specific reasoning they have for the specific occasion.
"
is what I wrote, but sorry this is what too expensive means, if you wanted it to mean something else to be useful to you ("too expensive for others"="not expensive for me"), this isn't what seems to be happening.
So you are saying that the economy would improve if people only did what was fun for them? That is what happens in hunter-gatherer societies. They have a lot of fun, but their economies are poor. There is no way the planet can support 8 billion hunter-gatherers. If we went back to that then billions of people would die, the very opposite of having fun!
I am saying that the economy would balance if people only did what is fun for them (not "was"), if people did less or more than what is fun for them constantly, then society wouldn't be fun this is what I am saying, together with the observation that keeping things funny, requires behaving.
For the ones who behave, they are fun for the rest people, for the ones who don't, they are not.
